It's weird, you try to be a good boy and post in the correct forum and then it gets moved into the wrong one!
Anyhoo, as much as I'd like to make things even clearer the first post pretty much says it all.
My "environment" is a decent PC that is kept up to date, uses a GTX670 graphics card (which isn't going to be scared of a plugin GUI, or two) and hasn't shown this fault before.
Grum.
